  • the present disclosure relates to a terminal device for determining validity of touch key input and a method and apparatus for determining validity of touch key input used for the terminal.
  • terminals such as smart phones and tablet Personal Computers (PCs) are becoming more and more popular.
  • PCs Personal Computers
  • the terminals have adopted touch keys for designs and convenience in use.
  • input of a touch key may be determined by measuring a capacitance change. That is, the terminal determines whether the touch key is input by measuring a capacitance change generated in the touch key according to user's manipulation. For example, as illustrated in FIG. 1A , the terminal determines that a user input is generated (typically by contact with a user's finger or a specifically designed stylus)in a section 102 where capacitance is changed, and the terminal performs a function corresponding to the touch key. For accuracy of the manipulation, the terminal may determine that the touch key is input if a capacitance change exceeds a preset threshold value. For example, as illustrated in FIG.
  • the terminal may determine that the touch key is input; in a section 106 where the capacitance is changed by the preset threshold value or less, the terminal may determine that the touch key is not input.
  • the touch key is located adjacent to a display region, and as result, a touch key may be unintentionally input during user's manipulation, as will be described with reference to FIGs. 1C and 1D .
  • FIGs. 1C and 1D illustrate examples of a terminal 100 in which touch keys 122a and 122b and a physical key 121 are disposed in a side of a display 110.
  • the touch key 122b is often unintentionally input.
  • the present disclosure has been made to at least partially solve, alleviate, or remove at least one of problems and/or disadvantages described above.

If the apparatus determines that input of the touch keys 122a and 122b is valid, it controls functions corresponding to the touch keys 122a and 122b to be performed. If the apparatus determines that input of the touch keys 122a and 122b is invalid, it controls the functions corresponding to the touch keys 122a and 122b not to be performed. That is, the apparatus for determining validity of touch key input determines whether input of the touch keys 122a and 122b is intended by the user and determines whether to perform the functions corresponding to the touch keys 122a and 122b.
  • the apparatus for determining validity of touch key input determines that input of the touch key 122b is not intended by the user and thus controls a function corresponding to the touch key 122b not to be performed.

If selection of a dummy key 123a-d is sensed at the same time as a touch key 122a-b, the terminal assumes the selection of the touch key 122a-b was unintentional, and the function corresponding to the touch key 122a-b is not performed.
